Tarrina Resources Advances Gold and Copper Targets with New Drilling Insights

Christmas Gift Drilling Uncovers New Mineralised Zones

Tarrina Resources (ASX:TR8) has wrapped up its Phase 1 diamond drilling program at the Christmas Gift Gold Project in southern New South Wales, with preliminary results indicating the gold system extends well beyond the historic mine boundaries. Six holes totalling 1,180 metres tested a northwest-striking magnetic feature, intersecting mineralisation that continues both northwest and southeast along strike. Notably, a new mineralised zone was intersected in two holes approximately 250 metres north of the historic mine, effectively extending the strike length by more than 500 metres.

The drilling confirmed the presence of zinc (sphalerite), copper (chalcopyrite), and pyrite mineralisation accompanied by silica and carbonate alteration, hallmarks of orogenic gold systems. Assay results for gold, zinc, and copper are expected by the end of May, following analysis by SGS laboratories in Orange.

Complementing the drilling, an extensive auger soil sampling campaign collected over 2,500 samples across strike extensions. Portable XRF analysis validated copper and zinc as effective pathfinder elements for gold, with strong anomalous zones identified over a 3-kilometre northwest trend from the historic mine area. These findings suggest the mineralised system at Christmas Gift could be substantially larger than previously understood, warranting follow-up drilling to test these anomalies for bedrock mineralisation.

The company’s approach to integrating soil geochemistry with drilling data aligns with its strategy to refine 2D and 3D geological models, enhancing targeting precision. This phase aims to validate historic drilling and lay the groundwork for future Mineral Resource estimation. The drilling also replicated historic high-grade gold intersections, lending confidence to the assay verification process.

Walparuta Project Reveals Significant Untested IOCG Targets

In South Australia, Tarrina’s Walparuta copper-gold project has advanced through comprehensive integration of geological, geophysical, and geochemical datasets. The company’s analysis identified a prominent coincident magnetic and gravity anomaly approximately 700 metres long and 330 metres wide, located down dip to the southeast of historic drilling and copper-in-soil anomalies. This anomaly, interpreted as a dense, magnetite-rich rock, remains untested and represents a prime target for further exploration.

Additional airborne geophysical surveys uncovered six more coincident magnetic-gravity targets sharing characteristics with known IOCG deposits in the region, including Havilah Resources’ Kalkaroo and Mutaroo projects. These prospects exhibit structural controls and alteration patterns consistent with IOCG mineralisation, supported by historic drilling that shows copper enrichment correlating with magnetite alteration.

The company plans further geophysical studies and field assessments to refine these targets, alongside relogging and pXRF analysis of historic core samples held in South Australian storage. This work aims to validate historic data and prepare for potential drilling campaigns designed to test the depth and extent of mineralisation.

Portfolio Advancement and Financial Position

Beyond Christmas Gift and Walparuta, Tarrina is advancing its Yongala copper-silver and rare earth elements project with geological mapping and geophysical surveys planned to identify high-priority drill targets. The company’s recent tenement application west of Walparuta expands its footprint in a geologically analogous area, underscoring its commitment to systematic exploration in the Curnamona Province.

Exploration expenditure for the quarter totalled $1.115 million, with no mining or production costs incurred, reflecting the company’s focus on early-stage exploration. Tarrina ended the quarter with a cash balance of $2.76 million, fully funding its planned activities. Related party payments included approximately $256,000 for outsourced mineral exploration services, consistent with ongoing operational requirements.

Pending assay results from Christmas Gift are expected to provide critical data to prioritize follow-up drilling, potentially unlocking new resource opportunities. The company’s methodical approach to integrating geochemical, geological, and geophysical data sets a foundation for advancing its projects toward resource definition.

These developments build on earlier announcements, including the commencement of drilling at Christmas Gift and the identification of untested IOCG targets at Walparuta, reflecting steady progress across Tarrina’s portfolio. The company’s strategic acquisition of Rox 1 and Rox 2 Pty Ltd in late 2025 consolidated key tenements, enabling a coordinated exploration campaign across multiple commodities and regions.

While assay results remain pending, the indication of extensive mineralised zones at Christmas Gift and the identification of large untested targets at Walparuta position Tarrina as a company to watch in the Australian exploration sector.

Notably, the company has maintained compliance with continuous disclosure rules amid recent market activity, having confirmed assay dispatch to laboratories in March and April, with results anticipated imminently. This transparency is critical as investors await data that could materially influence the valuation of these projects.
